Ads during the biggest game of the year were pricey in 2018 ($5 million for 30 seconds) - and companies are pulling out all the stops to build anticipation for some of the best commercials the ad world has to offer.

Turns out, the Patriots and Eagles aren't the only ones battling it out this year; Doritos and Mountain Dew challenged Peter Drinklage and Morgan Freeman to an epic rap battle.
